[PATCH 0/4] Test examples compilation externally

[PATCH 0/4] Test examples compilation externally

[David Marchand]

As DPDK provides examples compiled with makefiles, we need some tests in
the CI. So far, a few maintainers have been testing them but a simple
issue has been missed for some time and there was no way to try to build
all examples that were built with meson.

Additionnally, this series can help in identify issues in public headers
that the current headers check can not catch as it relies on the meson
framework for finding headers include path (which points at sources).

[PATCH 2/4] examples/server_node_efd: simplify build configuration

[David Marchand]

Rename sub directories in this example.
This removes the only special case in examples and will ease a next
change.

For the record.. it seems Intel CI is doing some funny thing.
I noticed before, so it may still be filtering out changes on the
documentation when applying patches...

So I'll simply ignore this report:

[PATCH 3/4] devtools: build all examples externally

[David Marchand]

So far, users of test-meson-builds.sh had to define their own set of
examples to build externally. This is not that great because users need
to maintain this list when examples are removed/added.

Rework the script so that the 'all' value triggers an automatic
discovery based on what was configured/compiled with meson/ninja.

Since the build has already been done in $build_path at this point, would
it be easier to get the list of examples from "ls $build_path/examples/dpdk-*"?

Oh yes, it is more robust than parsing ninja targets.
I'll look into it.

Indeed, I'll add a comment.

Scripts can be rather cryptic at times. I assume this sed statement is for

[PATCH v2 0/4] Test examples compilation externally

[David Marchand]

As DPDK provides examples compiled with makefiles, we need some tests in
the CI. So far, a few maintainers have been testing them but a simple
issue has been missed for some time and there was no way to try to build
all examples that were built with meson.

Additionnally, this series can help in identify issues in public headers
that the current headers check can not catch as it relies on the meson
framework for finding headers include path (which points at sources).


Changes since v1:
- reworked built examples discovery,

So far, users of test-meson-builds.sh had to define their own set of
examples to build externally. This is not that great because users need
to maintain this list when examples are removed/added.

Rework the script so that the 'all' value triggers an automatic
discovery based on what was configured/compiled with meson/ninja.

I think -e is not needed.
If you use -r, you can avoid backslashing the parentheses.

Indeed.

-r is not a posix option.

[PATCH v3 0/4] Test examples compilation externally

[David Marchand]

As DPDK provides examples compiled with makefiles, we need some tests in
the CI. So far, a few maintainers have been testing them but a simple
issue has been missed for some time and there was no way to try to build
all examples that were built with meson.

Additionnally, this series can help in identify issues in public headers
that the current headers check can not catch as it relies on the meson
framework for finding headers include path (which points at sources).

Changes since v2:
- tweaked patch 2 commitlog,
- dropped -e sed option in patch 3/4,

Changes since v1:
- reworked built examples discovery,

[PATCH v3 2/4] examples/server_node_efd: simplify build configuration

[David Marchand]

The server_node_efd example contains various binaries whose sources are
in sub directories that do not match their name.

Rename sub directories in this example and stop overriding the binaries
names in meson.build.
This makes a next change easier in the build scripts used by CI.

[PATCH v3 3/4] devtools: build all examples externally

[David Marchand]

So far, users of test-meson-builds.sh had to define their own set of
examples to build externally. This is not that great because users need
to maintain this list when examples are removed/added.

Rework the script so that the 'all' value triggers an automatic
discovery based on what was configured/compiled with meson/ninja.
